5) Establish the indentity (cot + tan ) sin = sec . Show each step to justify your conclusion.
katen-ka-za [31]

Answer:

Step-by-step explanation:

Identities : -

cot = cos / sin

tan = sin / cos

( cot + tan ) sin = sec

LHS

= ( cot + tan ) sin

= ( ( cos / sin ) + ( sin / cos ) ) sin

= ( ( cos sin ) / sin ) + ( sin² / cos )

= cos + ( sin² / cos )

LCM = cos

= ( cos² / cos ) + ( sin² / cos )

= ( cos² + sin² ) / cos

Identity : -

cos² + sin² = 1

= 1 / cos

= sec

= RHS

Hence proved.

Find the solution(s) to 22 +57-3 = 0. Check all that apply.
irakobra [83]

Answer:

x = -3 and x = 1/2

Step-by-step explanation:

To find the solutions to

2x² + 5x - 3 = 0

we can use the quadratic formula, as follows:

x = \frac{-b \pm \sqrt{b^2- 4(a)(c)}}{2(a)}

x = \frac{-5 \pm \sqrt{5^2- 4(2)(-3)}}{2(2)}

x = \frac{-5 \pm 7}{4}

x_1 = \frac{-5 + 7}{4}

x_1 = 0.5

x_2 = \frac{-5 - 7}{4}

x_2 = -3
